ABSTRACT

Provided are a detection device and method whereby it is possible to
accurately detect the presence or absence of a longitudinal tear in a conveyor
belt, while achieving high versatility and low cost. Embedded bodies 2
embedded at intervals in the longitudinal direction in a conveyor belt 17 each
comprise a passive IC tag 3 disposed at one width-direction end of the
conveyor belt 17, and a linear detection element 7 that is connected to the IC
tag 3, extends from one end to the other width-direction end of the conveyor
belt 17, and forms a loop circuit 9. Transmitted radio waves W1 are emitted
from a detector 10 toward the IC tags 3. Information from the IC tags 3
transmitted to the detector 10 by reply radio waves W2 emitted from the IC
tags 3 in response to the transmitted radio waves W1 is used to determine,
using a computation unit 13, whether the loop circuits 9 are energized.
Whether a longitudinal tear was generated in the conveyor belt 17 in the range
where the loop circuits 9 are embedded is detected on the basis of the
determination result.
